This wording is relative to N4917.
Modify [fs.path.itr] as indicated:
-2- A path::iterator is a constant iterator meeting all the requirements of a bidirectional iterator ([bidirectional.iterators]) except that, for dereferenceable iterators a and b of type path::iterator with a == b, there is no requirement that *a and *b are bound to the same object. Its value_type is path.
[ 2022-11-01; Reflector poll ]
Set priority to 3 after reflector poll.
Currently, [fs.path.itr]/2 effectively requires std::filesystem::path::iterator::reference to be a reference type, due to the requirements for (legacy) bidirectional iterators. However, it's reasonable for the operator* to return path by value, which can make the iterator model std::bidirectional_iterator, be compatible with std::reverse_iterator, and avoid complicated data structures (e.g. those in libstdc++) for achieving such purpose.libc++ is already doing so. I think we should make such a strategy conforming.
